Abstract

The increasing demand for portable operation has elevated power consumption to be one of the most critical design parameters. This paper presents various low-power techniques required for the design of portable systems. Low-power operation is achieved using reduced supply voltages (1-1.5 V) coupled with a system level optimization of the switching activity that involves logic design, re-synchronization, signal correlations and number representation. The support circuitry required for low-voltage operation is presented which includes level-shifters, DC-DC converters and D/A converters
